generalization vs specialization

Here, the inflorescence is highly reduced. It has a cup shaped receptacle formed by the fusion of five bracts. On the surface of this cup, generally a yellow coloured nectar secreting gland is present. A single female flower arises from the centre of the cup. It is highly reduced an..

Generally, the stems are aerial and grow above the soil surface. Sometimes, the stem becomes variously modified to perform special functions like perennation, vegetative propagation and food storage. The modified stems may be grouped under three heads viz, underground, sub..

Stem Modifications - Generally, the stems are aerial and grow above the soil surface. Sometimes, the stem becomes variously modified to perform special functions like perennation, vegetative propagation and food storage. The modified stems may be grouped under three heads viz, u..

Sometimes, a particular term satisfying certain conditions is required in the binomial expansion of the type (a + b) n . This can be done by expanding (a + b) n and then locating the required term. Generally this becomes a tedious task, specially when the index n is large..

The word root represents the number of carbon atoms in the parent chain and it is the basic unit of the name. The parent chain is selected as per the longest chain rule i.e., the parent chain is the longest continuous chain of C-atoms including the functional group and the multiple bonds, if any. ..

Inflorescence - Flowers are the reproductive structures in angiosperms. Each flower is a modified shoot adapted for purposes of reproduction. Flowers may occur either singly or in clusters. When clustered, the flowers are generally arranged on branches, which are quite distinct from the v..

These are land plants which grow in moist habitats and need well aerated soils. They prefer soil and air with moderate humidity. They avoid soils with standing water and soils containing great abundance of salts. They have some special features. Root system is well developed. Stems are ..

Ecological Adaptations - Mesophytes - These are land plants which grow in moist habitats and need well aerated soils. They prefer soil and air with moderate humidity. They avoid soils with standing water and soils containing great abundance of salts. They have some special features. Root ..

The meter scale enables us to measure the length to the nearest millimeter only. Engineers and scientists need to measure much smaller distances accurately. For this a special type of scale called Vernier scale is used. Vernier Calliper The Vernier scale consists of a main scale graduated..

The units of nervous system are specialized cells called the neurons . The general structure of a neuron is as follows: Around the cell body are short sensory projections called the dendrons. The fine branches of dendrons are called the dendrites. These short fibres receive mess..
